This is one I just finished up and am currently working up a load for it....73 cal, Mauser, paper patch 1OZ slug, 3 10 gauge wads. Slugs flatten out to average of 1-1/4 inches. Enjoy the pics....the cartridges for comparison are 265grn 35 Whelen.

Good Lawd! That thing could kill 2 Dinosaurs at once... one in front, and the one firing it! >:D
Seriously, that IS very cool. Would be interested in reading some more data on velocity, and kinetic energy from that beastie.

Wow! I love guns, and that good sir, is a very serious gun!
-
Why is the muzzle like that?
-
Now that's a bear stopper or is it for hunting engine blocks.
-
Thats some serious fire power rich, that is way cool
-
Charging bull Moose or Grizzer wouldn't stand a chance :o :o :o Love the mauser action and flash suppressor, looks absolutely wicked >:D...How's the recoil?

Way cool ! Bob

Thank you for the comments fellas. The only real purpose for these types is big game in thick cover and the closest I'm ever gonna get would be a black bear and that dont seem fair.....on the other hand if your gonna hunt 'em on the ground then it's going along.
This gun is about 100 years old and was factory converted about 90-95 years ago, so I'm working up the right load. There is no data for brass, smokeless powder 12 gauge slug loads. The issue is also the wads (no plastic in my guns) anyways I think I have it fairly close now. I'm right around 1580 to 1600 fps now, no signs of pressure either in case dimensions, primer measurements etc.
There is no reloading set-up. no press, dies etc. Old school hand work so here is some pics of my complicated set up.....ya right. The main deal with large bore, straight wall cases is not just the bullet weight but striking area of that bullet.
DC...that squared tube does 2 things....flash suppressor for vision in low light, but also works as an expansion chamber for the muzzle gasses. It flattens out the report to a very dull roar instead of a supersonic "blast".
Don, unkieford....when I pay my dime I want my ride....all of it. Recoil is not really all that bad but thats relative to the shooter. It's some stiffer than hot loaded 45-70-500
Pat, never give that a thought, but hell man ya never know if your gonna get caught in engine block stampeed >:D ;)
Thanks again fellas
rich
forgot to say the first pic ya see different colored primers....use magic markers to designate different charges in different loads ( color code)

There is a .50 cal AR that is called the Block Buster. It is used in the Mid East at check points to stop drive trough's.

Impressive gun. Lyman has a comprehensive shotgun reloading manual
-
Thanks Pat
Marc, I'm familiar with most reloading manuals. In this case the issue with using most load data is that the brass 12ga has significantly thinner case walls than the paper or plastic cases. The myriad of shotgun shell components will just flop around inside the brass case. There are a lot of loads for brass with black powder but none (by reputable institutions) for stacked oversize felt wads and the paper patched bullet. An example would be that I patch these slugs to an outside diameter of .750 for use in my .722 bore. Anyway I thank you for the information, sir.

Is the bore rifeled?
David
-
Runner, no sir it's smooth bore. That's why I paper patch to over bore dimensions. Sort of like shooting 45colt pistol rounds down a 410 bore. out to 75yds they are very accurate. ( accuracy is sufficient for sharp clean kills but not "tack-driver" size)

I did a lot of experimenting with shotgun slugs many years ago, both 12 and 20 gauge. Even though slugs are light compared to shot loads they actually benefit from slow burning powders giving you high velocity while keeping pressure down. It is surprising how the load and different types of powder affect the accuracy of the slug though.
-
I use to bench rest shoot thru the 80's and early 90'2.
I saw one of those, a guy there had. He said first one' he'd ever saw or held. Ithink he paid $175:00. I'd like to shoot a few doe's with it. Shoot the sholders to see how big it that oz. of lead will expand
A real stopper I'm sure.
-
Dang Rich that thing looks like it would kill in the front & cripple in the rear.
Is that the gun you were telling me about when we talked on the phone?
-
Nothing says 'STOP' better than a shotgun slug. That is an awesome piece Rich! I have slug molds and handload for my twelve guage. I got into it pretty heavy when the store shelves all ran dry of 30-06 rounds a couple of years back. (Insert quote from the movie Unforgiven - "I don't want to get killed for a lack of shooting back") ;) I have been experimenting with loads for a while. You are passed the velocity of lots of factory 12 ga. slugs already! Does your muzzle brake help much? The stock finish reminds me of my old Eddystone. I bet if you keep adjusting your load, you will find one that stacks them in a nice group out of those brass shells. How much does the gun weigh?
-
Marc, you are correct....I'm loading Hogdons Longshot which is a slow burner (as far as shotgun powder goes) but after this load I'm going to work one up for the .735 round ball with a "buck and ball" patch arrangement.
Crooket, Thanks sir
Trapper, this would be the one,sir
Howard, your right. When the purpose is intimidation (people) a big bore is the way to go. That finish is the original from about the 20's and the patina is great. It shoots fairly tight as is but I,m still working on the perfect paper for the patch. The thing about the brass cases and no crimp is ya glue in the paper patched bullet, I'm using both Duco and Seal-all right now. It's a little light (I'll weigh it today) I'm guessing maybe 6#....and ya do get your moneys worth on the recoil but I've never been sensitive to recoil. It's a fun gun to shoot.

Wow, that is a weapon of mass destruction right there. Destroys both the shooter and the shootee. >:D

Yeah, something about looking into the open end of a culvert sized barrel will hold your fascination!

Years ago my uncle interrupted some guys that were emptying his freezer. They pulled a gun on him and made him lie on the floor and made their escape. When the police were interviewing him they asked him how big was the barrel of the gun. My uncle put his thumbs and forefingers together and said."This frigging big!" It all depends on your point of view.
